I noticed this part was leaking oil. I was wondering what the part is and if anyone can share with me if there are seals or gaskets that are easy to replace on this to stop the leak? It's mounted to the engine under the starter. Thanks in advance.
Hydraulic fan pump?
Looks like it from that image. Try spraying some brake cleaner around the area and get it nicely cleaned up. Then you will be able to see exactly where the leak is coming from. You might be lucky, it could be nothing more than an O-Ring on one of the hoses. Hope for your sake that it is something simple because apparently there are no serviceable parts on the Fan Pump itself.
